Product Details

The circular water bath nitrogen evaporator (full stainless steel) adopts a circular structure for smooth rotation and utilizes purge and trap technology. It enables temperature-controlled heating of samples while rapidly, controllably, and continuously blowing inert gases such as nitrogen onto the sample surface to achieve fast, oxygen-free concentration of sample solutions. This method is characterized by time efficiency, convenience, and accuracy. It is widely used in food safety, pharmaceuticals, pesticide residue testing, clinical pharmacokinetics, and other fields.

Application Scope

1. Pesticide residue analysis: vegetables, fruits, grains, plant tissues, etc.

2. Pharmaceutical testing: traditional Chinese medicine production and drug testing

3. Environmental analysis: drinking water, groundwater, contaminated water, etc.

4. Biological analysis: serum, plasma, blood, urine

5. Commodity inspection: testing for dioxins, croft, etc.

6. Food and beverages: milk, alcohol, liquid beverages

Main Features

1. Utilizes water bath constant temperature with good and uniform heat transfer, facilitating rapid heating and temperature control.

2. The circular water bath nitrogen evaporator has strong compatibility, suitable for test tubes (diameter 10~29mm), conical flasks, centrifuge tubes, with a sample capacity of 1-50ml.

3. Available in 12 or 24 sample positions, with spring test tube clamp sample holders for fixed positioning, each sample position numbered.

4. Freely adjustable needle valve tubes allow independent height adjustment for each gas conduit based on tube size and solvent volume, with adjustable needle valves to control gas flow.

5. All components are made of high-quality stainless steel, resistant to acids, alkalis, and organic solvents, ensuring durability.

6. Equipped with an intelligent digital temperature controller, timer function, dual digital display, PID regulation technology, over-temperature alarm, and dry burn protection.

7. High-quality regulating valves ensure excellent air tightness and long-lasting durability.
